Executive Summary

This report provides a health assessment for the Aerospike cluster consisting of 5 nodes. Analysis identified 101,441,602 “Delete Not Found” events, suggesting application-side logic gaps.

NoteTAM Overview

The cluster is stable, but high DNF rates indicate unnecessary IOPS pressure. Reviewing application “blind delete” patterns is the primary recommendation.

Cluster Status Overview

Warning3.a: Config Symmetry

Detected 365 configuration drifts across the cluster.

Warning4.c: Delete Not Found

Detected 101,441,602 ‘Delete Not Found’ events across 5 nodes.

Observations and Remediation

3.a: Config Symmetry

Detected 365 configuration drifts across the cluster.

Recommendation: Check the Technical Details section to identify which specific parameters (e.g. memory, timeouts) differ.


4.b: Read Not Found

Detected 8,136 ‘Read Not Found’ events. This is often normal for application cache-miss workflows.

Recommendation: If the application expects all records to exist, investigate potential expiration or eviction issues.


4.c: Delete Not Found

Detected 101,441,602 ‘Delete Not Found’ events across 5 nodes.

Recommendation: This suggests the application is attempting to delete records that do not exist (Blind Deletes). Review application logic.


1.b: ENA Support Check

ENA Telemetry Missing: OS-level statistics were not found in this bundle.

Recommendation: To retrieve this data, run ‘collectinfo’ as root or use ‘asadm –lsmod –ethtool’. Manually verify with: ‘ethtool -i eth0’.


1.c: Version Consistency

Telemetry not yet ingested.

Recommendation: Review cluster telemetry and application logs for further investigation.
